    152 - Quantum Myriad and HPE GreenLake Storage Services

    152 - Quantum Myriad and HPE GreenLake Storage Services

    Two recents news invites me to think about this episode, first Quantum who introduces a modern file and object storage solution based on share-everything model, full NVMe and disaggregated architecture. A very good news for the champion of secondary storage. And the second HPE for its GreenLake storage services that recognizes once again its incapacity to develop file and object storage product by themselves. They're completely naked on this. They pick VAST Data, this is a fantastic news for VAST Data and a disaster for Qumulo. I hope you'll enjoy this episode.

    121 - Interview with Sumit Puri, CEO and founder, Liqid

    121 - Interview with Sumit Puri, CEO and founder, Liqid

    I visited Liqid at his HQ on Broomfield, CO, last June for the 44th IT Press Tour and clearly I realized that something is happening. This team is shaking the server and infrastructure established positions. So this interview became obvious and we decided with Sumit Puri, CEO of Liqid, to record it during VMware Explore. We covered the genesis of the company, the business and IT need of composability, the market dynamism around Composable Disaggregated Infrastructure or CDI, how the product works, the various use cases, the partner ecosystem and go-to-market, the pricing and of course the future. Lots of informations, Sumit shared lots of very interesting points and we anticipate a rapid acceleration in the coming months. Enjoy the listening, it is a great one, thank you Sumit.

    114 - Interview with Phil Bullinger, CEO, Infinidat

    114 - Interview with Phil Bullinger, CEO, Infinidat

    We visited Infinidat last April in Herzliya, Israel, for the 43rd IT Press Tour and I really wished to interview Phil Bullinger, CEO of Infinidat, as the company is really different from other usual suspects. So we took time together to talk and as you'll see we spoke about why he joined the company, the financial state of Infinidat, the current offering and differentiators an da bit of future. A very good episode again, Phil giving lots of informations, I hope you will enjoy the episode, thank you Phil and happy listening.

    111 - Recap of the 44th IT Press Tour

    111 - Recap of the 44th IT Press Tour

    The last IT Press Tour, Edition 44, was an amazing edition, meeting and visiting 9 hot companies like iXsystems, Lightbits Labs, Liqid, Nasuni, Quantum, Spectra Logic, VAST Data, Veritas and WEKA. It was the opportunity to get an update directly from top executives introducing new products, launching a new initiative or just updating their solutions. Again it was fantastic, beyond California we spent time in Colorado to meet Quantum at their EBC with manufacturing in Englewood, Spectra Logic HQ and manufacturing in Boulder and Liqid HQ in Broomfield. I made this recap to share our experiences and news, you can also visit the IT Press Tour web site to learn more. Enjoy.

    #167: NVMe-oF: Protocols & Transports Deep Dive

    #167: NVMe-oF: Protocols & Transports Deep Dive
    Abstract Block storage access across Storage Area Networks (SANs) have an interesting protocol and transport history. The NVMe-oF transport family provides storage administrators with the most efficient and streamlined protocols so far leading to more efficient data transfers and better SAN deployments. In this session we will explore some of the protocol history to set the context for a deep dive into NVMe/TCP, NVMe/RoCE, and NVMe/FC. We will then examine network configurations, network topology, QoS settings, and offload processing considerations. This knowledge is critical when deciding how to build, deploy, operate, and evaluate the performance of a SAN as well as understanding end to end hardware and software implementation tradeoffs. Agenda SAN Transport History and Overview Protocol History Protocol Comparisons NVMe/FC Deep Dive NVMe/RoCE Deep Dive NVMe/TCP Deep Dive Networking Configurations and Topologies for NVMe-oF QoS, Flow Control and congestion L2 local vs L3 routed vs Overlay Offload Processing Considerations and Comparisons Learning Objectives: 1) Cross Comparison of SAN transports; 2) First principles behavior for NVMe-oF transports; 3) Practical networking considerations for deploying NVMe-oF; 4) Implications of NVMe-oF transports for data flow and packet processing.

    #163: Automating the Discovery of NVMe-oF Subsystems over an IP Network

    #163: Automating the Discovery of NVMe-oF Subsystems over an IP Network
    NVMe/TCP has the potential to provide significant benefits in application environments ranging from the Edge to Data Center. However, to fully unlock its potential, we first need to overcome NVMe over Fabrics' discovery problem. This discovery problem, specific to IP based fabrics, can result in the need for the Host admin to configure each Host to access the appropriate NVM subsystems. In addition, any time an NVM Subsystem is added or removed, the Host admin needs to update the impacted hosts. This process of explicitly updating the Host any time a change is made does not scale when more than a few Host and NVM subsystem interfaces are being used. Also, due to the de-centralized nature of this process, it also adds complexity when trying to use NVMe-oF in environments that require high-degrees of automation. For these and other reasons, Dell Technologies, along with several other companies, have been collaborating on innovations that enable an NVMe-oF IP Based fabric to be centrally managed. These innovations, being tracked under nvme.org’s Technical Proposals TP-8009 and TP-8010, enable administrators to set a policy that defines the relationships between Hosts and the NVM subsystems they need to access. These policies are then used by a Centralized Discovery Controller to allow each Host to automatically discover and connect to only the appropriate NVM subsystems and nothing else. Learning Objectives: 1) Explain NVMe-oF’s discovery problem; 2) Review the network topologies that can support the automated Discovery of NVMe-oF Discovery Controllers; 3) Explore the differences between a FC SAN and an IP based SAN used to transport NVMe-oF/TCP; 4) Understand the proposed discovery process through in-depth review of the discovery protocol.

    80 - Interview with Eran Kirzner, founder and CEO, Lightbits Labs

    80 - Interview with Eran Kirzner, founder and CEO, Lightbits Labs

    Real pleasure to interview Eran Kirzner, CEO and founder of Lightbits Labs, being a pioneer of NVMe/TCP and the original believer, designer and developer of the TCP transport for NVMe. The momentum is now visible with some validations and adoptions by several giant vendors to initiate a tsunami. A good example is the recent validation of NVMe/TCP by VMware under the last iteration of ESXi. We learn more about the roots of the company, the original triggers of the project and other key information such financial trajectory. So a lot of good answers from Eran with the pleasure to have also Philippe Schwartz, partner at Square Peg Capital, who believes strongly in Lightbits Labs since the beginning of the project. Enjoy your listening and Thank you again Eran and Philippe.

    #98: Rethinking Ceph Architecture for Disaggregation Using NVMe-over-Fabrics

    #98: Rethinking Ceph Architecture for Disaggregation Using NVMe-over-Fabrics
    Ceph protects data by making 2-3 copies of the same data but that means 2-3x more storage servers and related costs. It also means higher write latencies as data hops between OSD nodes. Customers are now starting to deploy Ceph using SSDs for high-performance workloads and for data lakes supporting real-time analytics. We describe a novel approach that eliminates the added server cost by creating Containerized, stateless OSDs and leveraging NVMe-over-fabrics to replicate data in server-less storage nodes. We propose redefining the boundaries of separation within SDS architectures to address disaggregation overheads. Specifically, we decouple control and data plane operations and transfer block ownership to execute on remote storage targets. It also dramatically reduces write latency to enable Ceph to be used for databases and to speed up large file writes. As part of the solution, we also describe how OSD node failover is preserved via a novel mechanism using standby stateless OSD nodes. Learning Objectives: 1) Storage disaggregation; 2) NVMe over fabrics; 3) Ceph architecture.

    #97: Delivering Scalable Distributed Block Storage using NVMe over Fabrics

    #97: Delivering Scalable Distributed Block Storage using NVMe over Fabrics
    NVMe and NVMe over Fabrics (NVMe-oF) protocols provide a highly efficient access to flash storage inside a server and over the network respectively. Current generation of distributed storage software stacks use proprietary protocols which are sub-optimal to deliver end to end low latency. Moreover it increases operational complexity to manage NVMe-oF managed flash storage and distributed flash storage in private cloud infrastructure. In this session, we present NVMe over Fabrics based high performance distributed block storage that combines the best of both worlds to deliver performance, elasticity and rich data services. Learning Objectives: 1) NVMe, NVMe-oF for flash data path IO architecture; 2) Programming, architecture and optimization for flash; 3) Distributed storage, data services.

    #90: FPGA Accelerator Disaggregation Using NVMe-over-Fabrics

    #90: FPGA Accelerator Disaggregation Using NVMe-over-Fabrics
    Leveraging the NVMe standard to present FPGA accelerators as NVMe namespaces allows user space code to access accelerators as simple block devices via standard in-box drivers. NVMe-over-Fabrics (NVMe-oF) is a network protocol for NVMe that is used to communicate between a host machine and NVMe devices over high-performance Ethernet networks. Leveraging NVMe-oF allows an accelerator, that presents as a standard NVMe namespace, to be shared across existing transports such as RDMA, TCP/IP or Fibre Channel. With NVMe-oF, client machines can borrow accelerators over the fabrics connection which can then be accessed as if they were local to the system, allowing the same user code to run on direct attached accelerators and over-Fabrics accelerators. The ease and granularity available when setting up the over-fabrics connections allows servers to share accelerators on demand, allowing for the disaggregation of acceleration compute resources. Using NVMe Controller Memory Buffer (CMB), the fabrics connection is further improved by allowing devices to send and receive data directory from the accelerator without accessing host memory. We will discuss the advantages of accelerator disaggregation and its impact on resource usage. Learning Objectives: 1) Advantages and performance of NVMe for storage workload acceleration; 2) Performance of NVMe over Fabrics for storage workloads and acceleration; 3) Advantages of using Controller Memory Buffer coupled with NVMe over Fabrics.
